Application filed Ottober 13, 1 886. Serial No. 216,088. (No model.)

To all whom imcty concern: Be it known that I, NATHAN ORsoN GALx- INS,of Elm Greek, in the county of Buffalo 'Fig 2 is a vertical transversesection taken on line x fr in Fig. l. Fig. 3 is a horizontal sectiontaken on line g/ y in Fig. 2. Fig. 4 is a'detai-l view of one of theirons. Fig. 5 is a vertical transverse section taken on line z z inFig. 1. Fig. 6 is an inside View of one ofthe corners of the box. Fig. 7is a side elevation of a modified form. Fig. 8 is a transverse sectiontaken on line z' z in Fig. 7, and Fig. 9 is a detail view of one of thelatch-irons.

Similar letters of reference indicate corresponding parts in all theviews.

The object of my invention is to provide an efficient lock for fasteningan auxiliary wagonbox on top of'an ordinary box to increase the carryingcapacity of the wagon and to do away with slats and staples commonlyused.

My invention consists in a hook-latch of peculiar construction and aretaining device for holding the latch in a locked position, all ashereinafter more fully described, and pointed out in the claims.

rlhe wagon-box Ais of the usual description, and to each side-board B,near the middle thereof,is secured a strap, C, which is offset, forminga loop, a, for'receiving the end of the hook-latch D, which is pivotallyconnected with the auxiliary box E, placed on the top of the box A. Thelower end of the strap C is bent at right angles and extends under theedge of the sideboard of the lower box A.

.lo each side of the auxiliary box E, near the center thereof, issecured a T-shaped iron, b, having its upper end bentk at right angles,forming an arm, o, for engaging the upper edge of the auxiliarywagon-box E. The body of the T-shaped iron b isprovided with aperturedears cl for receiving the bolts by which it is fastened to the box, andopposite ends of theTshaped'head of the said iron are apertured toreceive bolts which are also employed to secure the offset-strap e. T0the T-shaped iron b, near the upper end thereof, is secured an arm, f,which is offset and projects downward a short distance over the face ofthe iron b, and is apertured to receive a bolt or rivet, g, which formsthe pivot of the hook-latch D, the latch being held in place and guidedby the offset-strap e.

Y To the wagon-box A is `secured an offsetstrap, h, at right angles tothe strap C, and be.

tween one end of the strap hand the side of the wagon-box `is pivotedthe latch F. The lower hooked end of the hook-latch D is beveled toallow the latch to compensate for the swelling or shrinking of the boxsides.

The locks applied to opposite sides of the wagon-box are similar butoppositely arranged with respect to each other, and are adapted to theposition in which they are placed.

To the lower edge of the sides of the auxiliary box E are secured clipsG, which embrace the upper edge' of the lower box and serve to make theconnection between the upper and lower box more rigid and positive. Tothe inner sides of the side-boardsof the auxiliary box are securedcleats z', which project below the' box and enter the corners of thelower or main box, A, to cause the boxes to register at the corners.When the auxiliary box is placed `on the main box, the hook-latch D isinserted between the strap h and the side of the box A, the latch Fbeing thrown back, and-when the auxiliary box is in place on the topofthe main box the hook-latch D is pushed forward into engagement withthe strap C, and thevlatch F is brought down against the rear edge ofthe hook -latch D, holding it rigidly in engagement with the strap C. Inthe inodied form shown inv Figs. 7 to 9 the iron b is provided with ashort sleeve, g', on which the latch D is pivoted, the latch being heldin place by the bolt h', which passes through the sleeve and through thebox E, thus forming a simple, strong, and inexpensive pivot for thelatch. A

Having thus fully described my invention, I claim as new and desire tosecure by Letters Patent-ab 1. The combination, with the main box A andauxiliary box E, of the offset-strap C, the T-shaped iron b, thehook-latch D, the oset IOO strap or keeper 7L, and the pivoted latch F,hung keeper, for holding the hooked latch in engagement With the strapC, substantially as described.

2. The combination, with the main box A and auxiliary box E, of thehook-latch D, provided with a beveled hook for engaging the strap C, andthe pivoted latch F, hung between said main box and a keeper oroffsetstrap, 11 for holding the hooked latch in engagement with thestrap C, substantially as described.

3. As an improved article of manufacture, a Wagoirbox lock formed of theT-Shaped iron I), the offset-armf, attached thereto, the hooked latch D,the strap e, secured to the T-shaped iron I), the offset-strap C, thcoffset-strap 7L,

and the pivoted latch F, hung between the main box A and theoffset-strap 71 substantially as described.

4. The wagon-box lock consisting of the L-shapcd hook-latch pivoted atits upper end and confined near itslower end Within a keeper oroffset-strap, the additional latch arranged to bear against theaforesaid latch, and the additional offset strap or loop to receive thefree end of the aforesaid latch, substantially as and for the purposeset forth.
